Vitamin K is well-established as a critical factor in blood clotting and wound healing, which are highly relevant to surgical recovery. Vitamin K (especially as mixed forms, such as K1 and K2) plays an essential role in the synthesis of clotting factors II, VII, IX, and X in the liver. Adequate vitamin K status helps reduce the risk of excessive bleeding during and after surgery. Scientific studies and clinical guidelines recognize the importance of correcting vitamin K deficiency prior to surgical procedures, particularly in patients on anticoagulant therapy (such as warfarin) or those with malabsorption disorders, liver disease, or poor dietary intake.

While vitamin K supplementation is not universally recommended for all surgical patients, it is standard care in individuals found to be deficient, or at risk, to ensure normal coagulation and promote optimal wound healing. Several clinical trials and reviews have demonstrated that vitamin K administration can quickly restore normal levels of clotting factors and reduce surgical bleeding risk. Additionally, vitamin K has been explored for its potential role in bone metabolism and tissue repair, though the evidence here is less robust than for coagulation. Overall, there is strong scientific justification, particularly in specific patient populations, for vitamin K supplementation in the context of surgery and postoperative healing.
